Thanks mate, I have just become possessed of a a beaut little D1 which is in half a dozen boxes so your videos are a real treat, I am also an aircraft engineer coming up on 50 years in the business so I get your procedural approach to rebuilding engines.
Really enjoyed the egine rebuild, greetings from England ps i use to work for quiten Hazel automotives in Redditch were they buily the Bantams i was told and sadly i signed on the Dole once at the old Enfield factory
Great video, it’s inspired me to build up my Bantam as it’s been dismantled and boxed up for more decades than I care to remember. I’ve owned about 10 D1s & D3s over the last 50 years and the most I ever paid for one was £5 and now I can’t believe how much parts are and reel at paying out £40 for an ignition cam and that’s assuming I can find one!!
Thanks Mike.......If you want to restore an old bike, you've got to be prepared to spend some money I'm afraid. But you also have to look at what recommissioned bikes are going for now days to. You certainly won't get a Bantam for 5 quid nowadays. Good luck with the restoration..........regards Bones
I really enjoyed watching the whole process. I would love you to rebuild my D14/4 but I caught your comment about being fully booked till 2024 and I’m in the UK. I wonder if there is anyone in the Uk that can rebuild a bantam engine to this standard?
@@OzBSABantams thanks Tony, I just watched the whole 6 episodes again, a joy to watch your attention to detail. I’ve bought some parts for my bike from Rex Caunt racing and Bournemouth Bantams so I’ll give them a call. Thank you for the reply. Dan
@@kevinjerome4925 The pineapple head Bantams (pre-53) didn't have head gaskets. The increase in compression would be marginal. The error in the castings of the heads from BSA would have more effect. I'm not sure where you're coming from in relation to a "modification".
@@OzBSABantams If the lack of a gasket meant that the compression was raised above the factory supplied specification and hence a power increase and performance, then for insurance purposes, this would be regarded as a “modification”. This would have to be declared to maintain valid insurance - just saying how it is!
@@kevinjerome4925 Hi Kevin.......The removal of a gasket .005" thick would barely have any effect on compression ratio and increase in power on something that was purported to be 4.5hp. The omission of the gasket reduces the combustion chamber volume by .02cc. The variations in manufacturing tolerances on the head combustion chamber profiles by BSA vary way more than that in combustion chamber volume, therefore I doubt you'd have any insurance issues. I'm not sure where you are, but insurance companies in Australia don't class that as modification as it has no real measurable effect on performance. We are talking Bantams with a compression ratio of only 6.5:1......It's very low. Appreciate your comments..........
@Tony Farmer hi yes I did hear that you did a few years back but thought I might try my luck ,I've got a friend over there atm so I might see if she could bring me 1 back 😉 Cheers.
@@philarbon7817 That's no worries, however there won't be any warranty support I'm afraid, as it's logistically too hard. Part of the reason I don't supply to the UK anymore.
Yep correct Bart. Plans were taken from DKW after Germany lost the war and many DKW 125RT copies were made in many countries. BSA decided to mirror image the DKW engine. Thanks for commenting.
